performance - Lenovo Y50 laptop does not perform well when Discharging

I just bought this laptop (Lenovo Ideapad Y50).

I'm playing games such as Battlefield 4 (upto date DLC) and WatchDogs. Even though I set battery manger to High Performance mode game doesnt works well unless I put back the Battery charger power cord to ON.

On Discharging my FPS in Battlefeld 4 (64slots server) - 30fps On Batter charging mode FPS 60fps both in HIGH Settings.

Lenovo battery manger set to Performance mode

Answer

NVIDIA cards and Intel chips are all sporting power saving features these days, and your symptoms will primarily have to do with the NVIDIA card's performance level when taken off AC power. Regardless of the user's preferences, these cards will automatically drop to a lower performance level when running on battery power.

It is possible to force them to maintain top performance while on battery, but registry hacks will need to be employed, and it will drain your battery in double quick time.

There's a long post about it here. By the time you get to the bottom of page 5 you'll have the registry values you need to solve the issue.

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
